Adding a 4th door

[boostat4500]

Has anyone here ever done or seen a 4th door on one of these burbs? I'm
thinking about doing it, but would like to talk to someone who has first. Thanks.

Someone, not sure who, posted this a while back.


I've been looking long & hard at the possibilities of making a 4 door burb out of one of these beasts. What I have come up with is this...(I have all of the stuff to do it to mine )

You will need:
pass side B pillar along with a set of 3rd door hinges
a pair of front doors(p/u is fine, burb would be better as you will need the window frame

First, remove the blank door panel & glass, ect...
Carefully remove the section of metal behind the door panel as you will need this for your door glass later on.

Next you will be cutting the drivers side B pillar out and moving it back to be the drivers side C pillar(with some mods to the top of it of course).

You will take the extra pass side B pillar and weld that into the drivers side. Some cutting & modifying will need to be done(striker pocket flipped to other side & hinge pockets move to other side).

Once you have this done, you can start on the 4th door. You should remove the skins from both doors and the window frames too. Cut both inner shells in half. You will need the "latch sides" of both doors shortened to the size of the 3rd door. Once welded together, you can weld in the hinge mounts to the front & remove the panel that would be behind the door panel & replace it with the piece you removed from the body in the first step. Once you are done welding it all in and installing any additional bracing(I would plate the welded areas from the inside and also plate the hinge area to be safe) You can re-skin the door using the removed drivers side skin, shortening it in the front, leaving the correct handle location then shave the lock hole out. Now is when if you used Burb front door for donors for the 4th door, you could cut up the window frames to make the new frames and reinstall the glass... As far as a rocker panel goes, I was going to section a drivers side front rocker panel to mirror a 3rd door rocker panel..

Awesome reply! Thanks a bunch for the info and ideas. I hadn't thought about the B and C pillar stuff you mentioned, great idea! It will have to wait till spring, when I can start riding my motorcycle again, but I think I'll definetly
give it a shot.
